It's understandable to feel concerned about unusual sensations like tingling, especially given your history of anxiety and the recent start of medication. Tingling in the thumb can result from various causes, including nerve compression, circulation issues, or even anxiety-related symptoms. Given that you've also mentioned feelings of depersonalization and derealization, it’s possible that anxiety may be contributing to your experience.

Explanation: Tingling, medically termed paresthesia, can occur due to several reasons:

• Nerve Compression: This could happen if you are resting your arm in a position that compresses the nerves, often leading to temporary tingling in the fingers and thumb.
• Circulation Issues: Reduced blood flow can also cause similar sensations.
• Anxiety: Anxiety can lead to heightened awareness of bodily sensations, sometimes interpreted as tingling or numbness.
• Medication Effects: While Lexapro (escitalopram) is generally well-tolerated, any changes you experience after starting a new medication should be monitored.

Next Steps:

1. Monitor Symptoms: Keep track of when the tingling occurs, its duration, and any activities before it starts (like certain positions or stress triggers).
2. Position and Activity Awareness: Pay attention to your posture and arm position during the day. Avoid resting your arm in a way that might compress nerves.
3. Stress Management: Since anxiety can exacerbate these sensations, consider implementing relaxation techniques such as deep breathing exercises, mindfulness, or gentle stretching to help manage symptoms.
4. Stay Hydrated: Ensure you're drinking enough fluid, as dehydration can contribute to various sensations, including tingling.
5. Evaluate Changes: If the tingling persists, worsens, or you develop new symptoms such as weakness, pain, or if the sensation spreads, take note and consider it a reason for further evaluation.

Remember that while it can be easy to feel alarmed by new symptoms, many cases of tingling are benign. Taking a proactive yet measured approach to understanding your sensations will be beneficial. If you have ongoing concerns or if you start experiencing distressing symptoms, it may be worth discussing these experiences with a healthcare professional.
